Application filed April 16, 1917.

T 0 all whom it may cancer Be it known that 1, WILLIAM T. Moons, a citizen of the United States, residing at Louisville, in the county of Jefierson and State of Kentucky, have invented certain better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure l is a side elevation, and Fig. 2 is a front elevation showing the application of the device, and

. Fig. 3 is an enlarged section on the line 3-3 of Fig. 1.

Referring; specifically to the drawing, 5 denotes the sound box of a talking machine, and 6 the stylus lever associated therewith. This lever has at its outer end a socket 7 in which seats and is held the needle or stylus 8. the device for holding the latter comprising the following parts:

To the socketed end of the lever 6 is applied a support comprising a yoke consisting of two branches 9 connected at one end by a cross-bar 1.0, and having at their op osite ends inturned terminals 11. The ever 6 seats between the yoke branches, with the terminals 11 engaging one side thereof and the cross-bar 1O spaced from the opposite side. as shown in Fig. 3.

The cross-bar 10 carries a sleeve 12 which is externally threaded to screw there/into, and the inner end of the screw bears against the lever 6. Thus, it will be seen that when the screw is tightened up, the yoke is secureiy clamped on the lever.

In the sleeve 12 is slidabiy mounted a plunger 13 extending at one end from the inner end ofthe sleeve and passing into a transverse aperture 14 in the lever 8, said aperture extending to the socket 7 so that this end ofthe plunger may engage that portion of the needle 8 which seats in the socket. Inside the sleeve, the plunger has specification of Letters Patent.

Serial No. 162,287.

an abutment 15, and a spring 16 is coiled around the plunger octween this abutment and a shoulder 17 in the sleeve. The spring tends to advance the plunger against the needle, whereby the latter is securely held in the socket. The outer end of the plunger projects-from the corresponding end of the sleeve and has a finger piece 18 to facilitate its manipulation. This end oi the plunger also has a side pin 19 seating in a slot 20 in the sleeve when the plunger is advanced. Upon retracting the plunger to disengage the needle and giving the plunger a slight turn to place the side pin across the outer end of the sleeve, the plunger is held retracted, and upon giving the plunger another turn to bring the side pin in line with the slot. the plunger is released and advanced by the spring to engage and hold the needle. The needle can therefore be easily and quickly applied, and removed, and the device can also be readily applied to existing machines, it being necessary only to drill the aperture 14: in the lever 6.

While the preferred embodiment of the invention has be illustrated, it will be understood that various changes and modifications may be made without departure from the spirit and scope thereof as claimed hereinafter.

I claim:

1. The combination with a talking machine stylus lever having a stylus socket and a transverse aperture leading to the socket; of a supporting; member having branches between which the lever is positioned and a crossbar. the branches having inturned terminals engaging the lever, an externally threaded sleeve passingthrough the crossbar and engaging the lever. and a spring actuated plunger mounted in ti e sleeve and. extending through the aforesaid aperture into the socket.

2. The combination with a talking machine stylus lever having a stylus socket and a transverse uDBTtlU'G lcadingr to the socket; of a supporting member on the lever, an externally threaded sleeve carried b member and engaging the lever to secure said member to the lever, and a spring"- actuatcd plunger mounted in the sleeve and of a supporting member on the lever, an .the plunger is advanced, and to seat across 10 externally threaded sleeve carried by the the outer end of the sleeve when the plunger member and engaging the lever to secure is retracted.
